Problems solved by technology

[0003] The purpose of the present invention is to provide a self-leveling load-bearing workbench for ships. By improving the traditional four-support technology, the existing leveling device can not be leveled in real time in the environment of severe swaying at sea, and the hull can be adjusted with the sea. When the wind and waves sway, keep the device on the carrying table in a horizontal state, and can also achieve horizontal leveling on land

Embodiment

[0028] Such as figure 1 , figure 2 A self-leveling load-bearing workbench is shown, including a load-bearing workbench surface, characterized in that: the load-bearing workbench surface 18 is a square flat plate, and a universal joint 4 is installed at the center of its bottom surface. A two-dimensional inclination sensor 10 is installed in the middle space, and the two coordinate axes of the two-dimensional inclination sensor 10 coincide with the two diagonals of the bearing workbench panel 18. The lower end of the universal joint 4 is installed on the base support 2, and the base 1. The upper part is rigidly connected with the base bracket 2, and the base bracket 2 is equipped with two sets of gear transmission devices, including motor drive gears 13, 15 and matching leveling gears 14, 16, such as Figure 4 As shown, the two mesh with each other. Motor drive gear 13,15 is connected on the output shaft of servomotor 7,9, and servomotor 7,9 is fixed on base bracket 2, and s...

Abstract

The invention relates to a worktable, in particular to an automatic-leveled bearing worktable for a ship. The device system comprises a two-dimensional dip angle sensor, a bearing worktable tabletop plate, a gear transmission device, a leveling rod, a support leg, a programmable logic controller (PLC), a servo motor and a motor drive thereof, and the like. The two-dimensional dip angle sensor is mounted in the center of the bottom surface of a worktable tabletop; and two coordinate shafts of the sensor are overlapped with two diagonal lines of the bearing worktable tabletop, so that the sensor can measure dip angles between the two diagonal lines of the worktable and the horizontal plane, and acquires two-dimensional dip angles of the worktable tabletop corresponding to the horizontal plane in real time, including x-axle dip angle signals and y-axle dip angle signals. The signals are transferred to the programmable logic controller through data wires; and the programmable logic controller calculates the inclination quantity and sends control signals in real time to control operation of the servo motor so as to adjust the leveling rod to always keep the tabletop in a stable horizontal state.

Description

technical field [0001] The invention relates to a workbench, in particular to a ship-used self-levelling bearing workbench. Background technique [0002] It is especially important to maintain the stability of the marine workbench when the hull is swaying with the wind and waves at sea. The stability of the table is mainly maintained by the leveling system. Existing automatic leveling systems mainly include three-support, four-support, six-support and other schemes. Three-support leveling has the advantages of simple structure, low cost, and easy maintenance, but poor anti-overturning ability; four-support and six-support have strong anti-overturning ability , but there is a problem of static instability, which is prone to virtual legs. This technical solution improves the traditional four-support technology, and divides the four supports into two groups, each group consists of two support legs, and the two support legs in one group are controlled by a servo motor to reali...
